Effect of method of sowing and seed rate on soil physico-chemical properties and nutrient content of wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted at the Instructional Cum Research Farm of the Indira Gandhi Krishi Vishwa Vidyalaya, Raipur, Chhattisgarh during winter seasons of 2015-16 and 2016-17 to study the effect of method of sowing and seed rate on soil physico-chemical properties of wheat (Triticum aestivum L.). The treatment combination of 3 methods of sowing viz. Broadcast methods of sowing (M1), Line sowing (M2) and Criss cross methods of sowing (M3) as main plot and 5 seed rates based on 100 kg ha-1 (SR1), 125 kg ha-1 (SR2), 150 kg ha-1 (SR3), 175 kg ha-1(SR4) and 200 kg ha-1 (SR5) sub-plot was laid out in split plot design with three replications. Results revealed that NPK content in grain and straw was obtained non-significant under methods of sowing and seed rates. However, maximum NPK content was observed in broadcast methods of sowing and seed rates 100 kg per ha-1. Different methods of sowing and seed rates were also found non-significant in available NPK in soil after harvest.
